DISPLAY CARTONS Filed June 14, 1960 3 Sheets-Sheet 3 United StatesPatent C) 3,009,622 DISPLAY CARTONS Salvatore J. Leone, Wallingford,Conn, assignor to The New Haven Board & Carton Company, New Haven,Conn., a corporation of Connecticut Filed June 14, 1960, Ser. No. 35,9262 Claims. (Cl. 229-16) This invention relates to cartons used fordisplaying articles for sale and ordinarily placed on counters, shelves,showcases, and other supports in retail stores. More particularly, theinvention is concerned with a novel display carton made of a singleblank of paperboard, which can be shipped flat in a carton containingthe articles to be displayed and can be readily erected at the point ofuse and loaded with the articles. The new carton may be used for holdingfor display a number of articles arranged in a plurality of rows and, ina typical use of the carton, it holds rows of erect card-s, on which thearticles are mounted in transparent enclosures. As all the advantages ofthe canton are realized, when it is employed in the display of articlesmounted on cards, a form of the carton suitable for such use will beillustrated and described in detail for purposes of explanation.

For a better understanding of the invention, reference may be made tothe accompanying drawings, in which FIG. 1 is a plan view of a blankwhich may be converted into one form of the new carton;

FIG. 2 is a view of the blank after the initial stage of folding in theconversion of the blank into a carton;

FIG. 3 is a view similar to FIG. 2 showing the blank glued to form thecollapsed carton;

FIGS. 4, 5, and 6 are views in perspective showing different stages inthe erection of the carton; and

FIG. 7 is a view in front elevation of the erected carton.

The blank shown in FIG. 1 is for conversion into a carton to be used inthe display of cards, on which articles are mounted, the carton holdingthe cards face-to-face in two rows extending from front torear of thecarton. The blank is made of any suitable carton material and comprisesa base 10 of oblong shape having a rear wall 11 attached to its rearedge along a fold line 12. A pair of U-shaped cuts 13, 14 are madebetween the base and rear wall to facilitate the raising of the wall byfolding on the line 12. A locking flap 15 is hinged to the outer edge ofthe rear wall and the flap has rounded corners crossed diagonally byfold lines 16. In its outer edge, the locking flap has a V-shaped notch-17. A flap 18 is hinged to the front edge of the base 10 and the flapis subdivided into a pair of locking tabs 19, 20 and other tabs 21, 22,and 23 lying at opposite sides of and between the locking tabs 19, 20.

A pair of outer side walls 24, 25 are hinged to the side edges of thebase and the rear edge of the wall 24 is connected to the adjacent sideedge of the rear wall 11 by a connecting panel 26, which is crosseddiagonally by a fold line 26a. Similarly, the rear edge of the wall 25is connected by a panel 27 with a diagonal fold line 27a to the adjacentside edge of the rear wall 11.

An inner side wall 28 is hinged to the outer edge of the outer side wall24 and a similar inner side wall 29 is hinged to the outer edge of theouter side wall 25. The inner side wall 28 is connected along its outeredge to a bottom wall 30 having a notch 30:: in its front edge and aflap 31 hinged to its rear edge. A similar bottom wall 32 is hinged tothe outer edge of the inner side wall 29 and the wall 32 has a notch 32ain its firont edge and a flap 33 attached to its rear edge.

A partition wall 34 is hinged to the outer edge of the bottom wall 30and a similar partition 35 is hinged to the outer edge of the bottomwall 32. Glue flaps 36, 37 are hinged to the outer edges of thepartition walls 34, 35, respectively.

In converting the blank into a carton in collapsed form, the blank islaid fiat and folded along the hinge line 38 between the outer side wall25 and the inner side wall 29 to cause the inner side wall to overliethe outer side wall and the bottom wall 32, the partition wall 35, andthe glue flap 37 to overlie the base 10. The glue flap 36 is then foldedinwardly to overlie the partition wall 34 and glue is applied to theupper surface of one or both of the glue flaps 36, 37. The blank is nextfolded along the line 39 between the outer side wall 24 and the innerside wall 28, so that the inner side wall overlies the outer side walland the bottom wall 30 and the partition wall 34 overlie the base withthe coated surface of the glue flap 36 moving into contact with theupper surface of the glue flap 37. When the glue has set, the conversionof the blank into a collapsed carton has been completed.

When the collapsed carton is to be erected, the outer side walls 24, 25and the rear wall 11 are folded upwardly and, in this operation, theconnecting panels 26, 27 are folded upon themselves along theirrespective diagonal fold lines 26a, 27a, so that the folded panels moveinward and lie in front of the raised rear wall 11. The raising of theouter side walls 24, 25 causes the bottom walls 30, 32 to move towardeach other and this movement causes the partition walls 34, 35, whichare connected together by the glue flaps 36, 37, to move upwardly awayfrom the base. The raising of the gear wall causes the flaps 31, 33attached to the respective bottom walls 30, 32 to be moved upward to liebetween the rear wall 11 and the infolded doubled panels 26, 27. Beforethe outer side walls 24, 25 have been fully raised, the locking flap 15attached to the top of the rear wall is folded downward in front of therear wall to a position in front of the folded panels 26, 27 and theflaps 31, 33. The presence of the notch 17 permits the locking flap topass to the rear of the rear edges of the raised partition walls 34, 35and, as the locking flap 15 is swung downward to a position parallelwith the erect rear wall 11, the corners of the locking flap outside thefold lines 16 flex and pass to the rear of the rear edges of the innerside walls 28, 29. In its final position, the locking fiap is heldfirmly in place with its ends and middle portion behind the rear edgesof the inner side walls and of the connected partition walls,respectively. In this position of the flap, it overlies the infoldedpanels 26, 27 and the flaps 31, 33 attached to the bottom walls 30, 32and prevents the sections of the panels from spreading apart. Thisaction tends to maintain the outer side Walls 24, 25 erect.

As the final operation in erecting the carton, the flap 18 attached otthe base is folded upward and inward over the base. At the same time,the outer side walls 24, 25 are forced toward each other, so that thebottom walls approach each other and raise the partition walls 34, 35still higher. When the bottom walls have approached each othersufficiently, the locking tabs 19, 20 on the fiap 18 are forced into thenotches 30a, 32a in the front edges of the bottom walls and the tabsthen hold the bottom walls from moving apart. This prevents the outwardlowering movement of the inner and outer side walls and the flatteningof the partition walls by a movement toward the base. As the flap 18 isswung inwardly over the base, the tabs 21, 23 are inserted beneath theouter edges of the bottom walls 30, 32 and beneath the inner side walls28, 29 and the tab 22 is inserted beneath the partition walls 34, 35 andbeneath the inner edges of the bottom walls. On completion of theseoperations, the carton is erected and ready for use.

The inner side wall 28 and the opposed partition wall 34 are providedwith registering openings 28a, 34a respectively, for receiving the endsof articles and, since the carton described is to support cards on whichthe articles are mounted, the openings are slots wide enough to receivethe cards. The inner side wall 29 and the opposed partition 35 aresimilarly provided with registering slots 29a, 350, respectively. Theslots are spaced the proper distance, so that the cards with the objectsmounted thereon can be placed in adjacent slots, and when the carton isloaded, the objects are arranged in two rows with the front object ineach row fully visible.
